[Ghost] DNA from an unknown ancient ancestor of humans that once bred with Denisovans still exists among the genomes of people today, a study has revealed.
The different branches of the human family tree have interbred and swapped genes -- a processes known as 'introgression' -- on numerous occasions...
Experts from the US found that some three per cent of the Neanderthal genome came from interbreeding with another ancient human group 300,000 years ago...
The researchers used the algorithm to look at genomes from two Neanderthals, a Denisovan and two African humans.
Alongside finding that a small proportion of the Neanderthal genome came from ancient humans, the team also determined that one per cent of the Denisovan genome appears to have come from an unknown and more distant species.
Moreover, up to 15 per cent of this 'super-archaic' genetic material has likely been passed down into modern humans who are alive today, the researchers said.
While it is not clear exactly from which species these fragments of DNA originated, the team suspect that they may have come from Homo Erectus...
Bone and ivory beads found in the Denisova Cave were discovered in the same sediment layers as the Denisovan fossils, leading to suggestions they had sophisticated tools and jewellery...
DNA from molar teeth belonging to two other individuals, one adult male and one young female, showed they died in the cave at least 65,000 years earlier.
Other tests have suggested the tooth of the young female could be as old as 170,000 years.
A third molar is thought to have belonged to an adult male who died around 7,500 years before the girl whose pinky was discovered.

Probably the people of Minneapolis... :)
“So there is hope that things will clear up as long as we dont regress into idiots”
Yes, but I doubt that DNA will tell us if there were earlier civilizations that got wiped out by glaciation.
They were sunning themselves on top of some cliffs when some tricky monkey-man clubbed 'em out.
I was interested in my Neanderpercentage, had some, but also showing up were the Denisovans, bunches of other archaic DNA. I feel so smug about this. :^)
The DNA bit was just **an example** of new things that have come down the pike that tell us about out history. Sorry if I misled you.
Forgot to include the huge advances in satellite imaging using LIDAR and GPR which is uncovering lost cities all over South and Central America. Part of the problem in the past is we just did not have the tools to look beyond the obvious or what the naked eye can see. Now we are acquiring some of what is need to see into the distant past of human civilization.
But the ice cities of the Neanderthals melted and can never be found :)
However, the comet strikes of 10800 BC is now being heavily researched and many previous mysteries are being solved: why did the mega-fauna disappear? what happened to the Clovis peoples? how did the Younger Dryas (real climate change) start and end?
Graham Hancock’s “America Before” has a section on what it might have been like to have lived through the strikes which likely lasted 100 years; to us, it would be unimaginable horror. But it does explain the worldwide pre-history obsession with astronomy
“Sorry if I misled you.”
No, you didn’t. While I am certainly not a scholar, a lot of those things get posted here, and my battered, tattered brain takes in as much as it can.
SC: Time for you to post Firestone et al.
Ooooh, not a bad idea...
